MySQL Programming Tutorial

Learn SQL step-by-step using MySQL: from installation to writing efficient queries with joins, aggregates, transactions, and constraints.

ANY and ALL

Compare a value to any or all values from a subquery. These operators help benchmark against a set of computed values.

Example
SELECT * FROM orders\nWHERE total >= ALL (SELECT AVG(total) FROM orders GROUP BY customer_id);
  • ANY means “at least one”; ALL means “every value”.
  • Pair with aggregates in subqueries to create meaningful thresholds.

Practice as You Learn

Use the MySQL editor to run queries and adjust examples. Build confidence by experimenting with different WHERE clauses, JOINs, and aggregates.
